DYEING APPARATUS.

Application fled January 12, 1928. SerialNo. 246,131.

This invention relates to dyeing apparatus, and aims to provide meansfor dyein different parts of an absorbent mass with 'fierent colors.

A particular object of the invention 1s to provide a machine forspotting yarn while the yarn is wound in a mass, and to produce bands ofdifferent colors around such a mass, each band extending from the outerto the'inner surface of the mass.

The invention may best be understood by a detailed description of apractical machine embodying it. Such a machine is shown in theaccompanying drawings, in which Fig. 1 is a plan view with the b'aseplate partly broken away;

Fig. 2 is an enlarged longitudinal section taken on the line 2-'2.ofFig. 1;

Fig. 3 is a horizontal section taken on the line 33 of Fig.4.; and t IFig. 4 is a transverse section on the linea -4 of Fi 1. I Y

Th machine shown has a base plate B which ma be supported at about theheight j '26 of-an or inary work bench by means not shown in thedrawings. On the base plate B is mounted a pumping deviceP and a workholder W. In the operation of the machine, the pumping device drawsdifierent' colored dyes from a plurality of separate reservoirs,

T, T, T, T, and forces limited quantities of the difi'erent colored dyesinto separate portions of a cone of am on the work holder W'.

'Therpumping. evice P includes a cylinder 3 block P containing aplurality of vertical, bores P, P P P all of WhlCh are closed at theirlower ends except for small drain openings P, communicating withvalve-controlled drain pipes P extending through an opening'in the plateB. The pistons P, P P, P of the pumping device are driven from a shaft Pmounted on the lower side of the plate B and driven thro. gh a pumpingpress clutch so that it may be given a single revolution when desired bythe operator. n the shaft P is a crank P connected by means of aconnecting rod P to the free end of a lever P fulcrumed on a bracket, Pmounted on the cylinder block P The lever P" is connected by alink P toa slide P" mounted on a vertical rod P, which isslidable in two bearin sP formed on the cylinder block P The plstons are connected with theslide P so as to be reciprocated thereby.

The length of the stroke of the slide. P may be varied by attaching theup er end of the connecting rod P in any one .o the number of holes P inthe lever P. The lengths -of the strokes of the individual pistons mayalso be adjusted. In the form illustrated, the pistons P and P aredirectly connected to the slide P, so that their strokes are the samelengph as that'of the slide, while the pistons P, are connected to theslide in: such away as to allow for a-regulatable amount of lost motion.For this urp'ose, the iston rods P ofthe pistons P, are slida le inholes in the slide P and are provided with fixed collars P below theslide, and adjustable collars P and P 'above the slide. It is a parentfrom this arrangement that the stro e of the piston P is less than thestroke of the slide P by the amount by which the distance between itscollars P and P exceeds the thickness of the slide. Thus with theadjustment shown in Fig. 4, the piston P has a stroke shorter than'thatof the pistons P and P, which move with the slide, and longer than thatof the piston P.

. The inlet openings P 3 P P P of the cylinders are connected by pi es1? to the separate dye reservoirs T, T", T which may be located belowthe plate B. glach of the pipes P contains a check valve An outletopening P located near the bottom of each cylinder, communicatesdirectly with one of a plurality of injectors J, J, J J d attached toone side of the cylinder block.

Each injector comprises a double nozzle J and two needles J 2 fixed inthe discharge openings of the nozzle. The nozzle J has a body J 3 on therear end of which is a threaded stem J which is screwed into anip'ple J5 attached to the cylinder block P over one of the outlet openings P Thestem J con- ..tains a nozzle bore J 6 which is the intake opening of thenozzle J In an enlarged bore in the front portion of the body J 3 islocated 3. Chuck J containing two longitudinal bores J whose outer endsform the discharge openings in the nozzle J To permit com ression of theinner portions of the bores J 1n order to grip the needles therein, therear portion of the chuck contains a diametrical slit J at the inner endof which is a transverse bore J extending across the two bores J and atransverse slit J The chuck J is retained in the body J 3 by a nut Jwhich is screwed on the front end of the body and engages the chuck J soas to force the conical inner end J of the chuck against a conical seatin the body. The chuck J has at its outer end a projection J which isthrust intothe mass to be dyed when the mass is brought into operativerelation with the injector. On the outer end of the nut J is an annularprojection J lying some. distance behind the outer end of the projectionJ Each of the needles J has a solid rear end portion J which is clampedin the inner portions upon the bores J by screwing the nut J inward. Asthe shaft of the needle is of uniform diameter, it may be gripped at anypoint by the chuck, so that the distance which it projects beyond theend of the projection J may be varied. The needle has a pointed frontend whose apex J is its axis. The needle contains an open longitudinalgroove J 21 which extends from the portion of the needle crossing thebore 13 as nearly as possible to its apex J The work holder WV comprisesa carriage -W carrying a standard W in which a shaft W is rotatablymounted. On one end of the shaft W is a cone holder W adapted to carry acone of yarn C by engagement with the card-board core C on which such acone is ordinarily wound.

The carriage Vv is reciprocatable in directions parallelto the needles JJ and adj ustable transversely to the needles. The carriage is slidablymounted on rods VV fixed on a'frame V which is mounted on a transverserod adjustably secured in standards VV projecting up from the plate B. Ashaft WV rotatably mounted in similar standards W assists in supportingthe frame Y9 and provides for reciprocating the carriage V on the rodsFor this purpose, the shaft W fiis provided with a gear W meshing with arack l/ 15 on the bottom of the carriage. A handle W is provided forturning the shaft The shaft W and the cone holder W are colors. After acone has been placed on the cone holder \V, the carriage is movedtowards the injectors by turning the handle V until its movement isarrested by an adjustable stop W. This causes the needles of eachinjector to penetrate the yarn. The slide P is then given. a singlereciprocatory movement which forces the different colored dyespreviously drawn into the bores of the cylinde'r block through theseparate injectors into the portions of the cone immediately surroundingthe needles of each injector. The carriage W is then returned to theposition shown in Fig. 1, the pawl and ratchet W", VV' causing a slightrotation of the cone C during the latter part of this movement. Theoperation is then repeated until four separate zones C C (1 C, eachextending completely around the cone and extending from its outer to itsinner surface, have been saturated with the four differently coloreddyes. I

Substantially uniform saturation of the yarn in each of the four zonesand uniform Width of the four zones is secured by forcing a greaterquantity of liquid into the zones which are of larger diameter andconsequently of larger volume. The quantity of dye injected into eachzone of the cone is measured'by the volume of the portion of one of thebores below its piston when the piston is at the upper end of itsstroke. From the connections between the pistons and the slide P alreadydescribed, and the setting of the collars P and P of the pistons P, P,it is apparent that the smallest quantity of dye is injected into thezone C nearest the smaller end of the cone. A larger quantity isinjected into the zone C while still larger quantities are injected intothe zones (1 and C This arrangement has proved satisfactory in practice,but it is apparent that, if desired, the machine may be arranged toinject different quantities of it into the zones C and C by connectingthe piston P to the slide P in the same way as that in which the pistonsP and P are connected thereto.
